The particular illustrated embodiment ot my invention comprises a base member rep- I resented at 13 and formedof a pair ot longitudinally-extending bars in the Jform oi'. pipes 14 which are disposed in parallel ref lation and `are connected together atV one end by a cross-piece 15 and at their opposite end by a cross-piece 16, the bars 14 at'the ends thereof adjacent the cross-piece 16 being outwardly diverging as represented at 17, with their ends turned .'downwardlyas represented at 18 to formv feet' atwhich the base member is adapted to rest at one end on the oor. In this connection it may be stated that the provision of the divergent portion 17 affords arelatively broad'bearing for the base member, in its support konthe floor, and also affords handles bywhichthetablemay bev gras ed tor littingthe table at this end f'to' w eel it about on wheels `hereinafter referred to, inthe same way that a wheelbarrow is operated.

Surmounting thebase member 15 is a rocking-trame 19 formedy of a casting 2() located in a plane between the members 14 and having laterally-extending bosses v21l forming trunnions journaled in upright lugs 22 rising from the members 14 at the ends. thereof adjacent the cross-piece 16. Then casting 2() is provided with two tubular( members 23 and 24 disposed at a right angle to each other and extending intoV a plane.v

parallel with thev members 14, the memberl 23 in the position of the structure shown invk adapted to extend into any one of a num-` ber of notches 29 provided in'theside of the rod 25, and by interlocking with the notch of any particular one, of the notches 29 hold the member in such adjusted position. The rodv25 serves as a support for one of the vsections ofthe table-top, this section, which is represented at 30 and is preferably upbolstered as shown, being located at the footof the table. The support of the table section 30 on the member 25 as stated is Veffected through the medium of a frame 31 formed of side Vmembers 32 and cross inembers 33, 34 and V35, this frame being pivotally connected at one end with the upper end of the member 25, as lthrough the medium of a pivoting rod 36 secured in the upper endyof the member 25 and projecting at its opposite ends therefrom, at right angles to the axis of the table, the outer ends of they pivoting;1 rod 36 passing through depending lugs 37 on the cross-piece 35 and affording journal connection therewith, whereby the frame 31, with the table section 30 supported thereon, may be adjusted in va vertical plane on the member rEhe table section SO is provided toward the end thereof opposite to which itis pivoted on the member 25, with a yoke-shaped frame 38, betweenv the depending` lug portions 39 of which the closed end of a U-shaped `frame 40 extends and is pivoted as through the medium of the rod 41. The sides of the frame Ll-O are in the 'form of rods aarallelino' each other and having)v slidii support in bearing portions 42 of the cross-,piece rEhe table-top 2130 while.'being` supported on the top of the frame 31 vis free to slide lengthwise thereon for purposes ofadjustiiig table section 3() along4 the table, a set-'screw e3 screwing in one of the guide portions 4-2 and against one of the rods 1-1 serving; to hold the tabletop in adjusted position on the frame '31.

rEhe crosspin 36 also serves as a support for a foot-rest represented at 44 which extends beyond the table-section 30 and is in theA form of a U-shaped frame, the side memberspof which are represented at 15 and l lthe cross-piece thereof, which forms a platform upon which the patient may stand, at ,46. The foot-rest frame is pivoted on the rod 36, and co-operates yat a cross-bar 117 j thereon with a releasable locking device on l36 from the position therein shown. The

member 50 is provided with two seating sur" faces, the upper one of which cosoperates with the seating surface afforded by the member 49 to hold the foot-rest in the .posin tion shown in Figs. 1 andA 2, its other, lower, seating surface yrepresented atl V52 being adapted to support the foot-rest in lowered condition. v f

vThe table-.section 30 co-operates with vmeans for holding it in the desiredl adjusted position on'the member .25, this means comprising' a rod 53 pivotally connected as indi cated at 5e to depending lugs55 on the cross-piece the rod 53 telescoping with the tubular member 56 which is pivotally connected at 57 to upwardly-extending ears 58 provided on the tubular member 2li. The rod 53 slides in the member 56 and is adapted to be releasably held in adjusted position by means of a device 59 suchas that illustrated at 26 and hereinbefore described,

and comprising` a sliding` rod on the member -56 yadapted to enter any one of the openings 60m the side of the rod 53. The head portion of the table isvformed of a section 61 preferably upholstered as shownand involv p ing a framework 62 at its under sideof which the cross-bars 63v .are parts.

The rod 64s telescopes with a tubular member 6'?k rigidly connected with the outer end of a bar 68 i telescoping with the member 24 and adapted to be set in adjusted position therein by meansof a set-screw 69 screwing in the member 24 and against the rod-68. The lower end ofthe member 167 is provided with oppositely-,extending sections 70 extending` crosswiseof the machine and in` which a shaft carrying supporting wheels 71, is journaled. The rod 611 is adjustable in the member 67 lengthwise of the latter and is shown as held in adjusted position by means tof ,the i device 72,;like .the ldevice 2610i?

Figs.. l land ..2Wherein the table top, generallystated, extends.horigkl Zontally..from. ,whichxit Willofccourse be understood thatthe., various sections f of the 1329 table top may assume any. desiredinclination relative vto each other, andas means for firmly holding the table in such position, I lprovide the catch mechanism illustrated more particularly in Figs. 8, 9 and 10 and involving a latch represented at 105, provided as an upwardextension of a sleevemember 106 which surrounds an eccentric 107 mounted on a shaft 108 journaled in depending lugs 109 on the ends of the members 14 adjacent the cross-piece 15, the shaft 108 being provided with operating handles 110 through the medium of which the shaft may be turnedfor actuatingthe est eccentric 107. rEhe latch-portion 105 is formed vwith a shank section 111 which lpasses guidingly through the eye-portion 112 of a rod 118 mounted in an opening 11e in ythe cross-piece 15. Y The outer end of the rod 113 is provided rwith a nut 115 screwed thereon and. which, in connection with a coil spring 116 surrounding the rod at the opposite side of the cross-member 15 and located therebetween and between the shoulderA presented by the eye-portion 112,- operates to position the rod 113 on the member 15 Vand thusrelative to the eccentric 107, it being understood that upon rotating the nut 115 in a directionk to un- 'the parts of the table are in the position Figs. 1 and 2. By manipulating shown 1n the nut 115 the latch 105 maybe adjusted into and out of a position in which, when the shaft 108 is rotated inclockwise direction in Fig; 2 to the position therein shown, the latch 105 will be carried into the eye 117, and by reason of the eccentric action produced on this `latch by the rotation of the v shaft 108, the supporting base 13v and Vthe structure hereinbefore described, and shown, I,

as pivoted thereto at the trunnions 21, may be caused to assume the position shown in Figs. 1 and 9, wherein the support of the table structure at this end of vthe table is lat the rollers 71,' and the adjacent end ofk the base member. namely, the endthereof at the left in Fig. 2, 'is raised fromthe floor, thereby causing the parts described to be firmly locked together and a secure foundation for the device afforded. Furthermore, inthe locked condition stated the device may be wheeled aroundy the room in the same manner that a wheelbarrow is, as hereinbefore explained.

As will be understood from the foregoing, the table-top structure formed of the several independently-adjustable sections, is pivotally supported to move asa unit through a vertical plane, the table, aslprefer to construct it, occupying no rmally the position in which the table-top extends substantially' vertically or in slightly inclined position from the foot portion thereof toward the head-portion, whereby in positioning a patient for manipulation, or for other .treatment, or examination, the patient instead.

of climbing upon the table-top in horizontal position may be readily positioned on the table-top by steppingv upon the foot-rest` with the back of the patient opposing the' table-top portion, and the table-top structure as a whole swung `downwardlytov horizontal or substantially'"horizontal position. The means shown'for causing the table-top and its direct supporting means to assume the y upwardly-extending position referred to, are in the'form of coil springs 118 lo-f cated in the members 18 Vand interposed between extensions 119 on the cross mem# f ber 15 and the ends of a cross-head 120 which extends at reduced portions 121 there-y of into, and is slidable in, slots 122 formed inthe opposing sides of the members 18 and extending longitudinally thereof, the cross-head 120 having pivotally connected ytherewith at their lower ends, bars 123 which incline upwardly and lare pivotally 7 connected with the upper end ofthe member 19 at the opposite sides thereof as indicated at 124, these springs y118 being constantly under compression and serving to yieldingly force' the cross-head 120 to the right in Fig. 8 and consequently through the medium of the bars 128 swing the tabletop portion toward upright position. y In this connection it may be stated that under certain conditions it may bey necessary for the operator to force the table-top lstructure from the position it occupies when the patient steps upon` the foot-rest `and positions himself, opposite the table-top, to the horizontal position shown in Fig. 2, in whichy case the stirrups 82 afford a convenient means of applying the desired downward pressurek on the free end of the table-topto swing vit down to the horizontal position in which it may be locked as hereinbefore explained. V

The apparatus is provided with means for swinging the table-top portion into subk stantially upright positionwhen it is desired to` remove the vpatient from the table,-

these means, as shown, involving the use of fluid-pressure, preferably' air under pressure, operating against the cross-head through the medium of piston and rcylinder mechanism, the cylinders of which are represented at 125, these cylinders being` ar-r ranged in parallel relation between the members 13 and connected togetherthrough the medium of an end plate 126 connected with table-topp the su `sure tothe cylincers to swing the table-top the members 13, these ycylinders' extending toward the .right-hand end otthe lmachine inFig. 2. Slidable in the cylinders are pistons128, the piston Arods 129.01 which are connected with the cross-head 120. 1The `cross-head 120 connects with a rod 130 to the opposite end oi. whicha piston1131 connected, this piston1 sliding in a cylinder 132 secured Ato a .web connecting'the members 13 at the .rightfhand'end ot' the yapparatus in Eigj, the ypiston 131 and cylfinderl 132 serving asa cushioning means `in theoperation oi the vpiston and cylinder 'mechanism' 12544128.

ln the particular arrangement shown valve mechanism is provided for controlling the introduction orp -luid-pressurel.into the cylinders125,I and the exhausting ot 'the saine theretorm, to Lcontrol the movement ot the plying ot the Huid-presupwardly, being an automatic operation oc curi-ing upon the act ol" releasing the latching mechanism which holds the table down invliorizontal position, ashereinbe'lore veirplained. rrhe valve mechanism reifer'red -to comprises a .valve casing 134 with which communieatesl a pipe 135le'ading 'trom anyV suitablesource of fluid-pressure, for eX- ample compresserL air, the vcasing 134 containing at its opposite ends plugs 136y andv 137, with an apertuied.valve-seat partition 133` interposed between, and spaced from7 the innen ends ot these plugs.v rThe space between the plug 136 and the partition coi'i'nnunicates with a passage 139 in rthe member 134 which opens into both ot the cylinders 125 at the eXtreir lett handy ends thereof shown in Fig..14. rIhe valveproper oit' the valve-device, which is represented at 140 and, is located between the partition 138 and the plug 13T, is adapted to cooperate with the seat 141 provided in the partition 133, this valve having a stein 142 which is guiding-ly confined at one end in a slot 143 in the plug 13'?, acoiled spring 144 surrounding the stem 142 and confined between the plug 137: and the shoulder 145 on the valve140, operating to yieldingly hold the valve 140 in closed position'against the seat 141. The plug aperture 146 extending.entirely.l therethrough rlhe latter extends outwardly beyond i the plug 136 and is adapted when torcedinwaidly toA unseat the valve 140. The plunger 14T cooperates with a bell-crank lever pivotally connected, as indicated at 149, with the end-piece 15, the forwardly-extending arm-portion 150 of this lever opposing the outer end ot the plunger' 14T andv the trans versely disposed arm-portion 151 ot this lever carrying a threaded rod'152 screwed into this arm and extending lengthwise ot the apand in line with the member vThe chamber 157 located 136 contains an tblfftolb in which a plunger 141 isslidingly mounted.
